KYA 0.80mm Automatic Rebar Tie Wire is a 21 gauge galvanized low-carbon steel tying wire supplied on 100m reels for compatible automatic rebar tying tools. Each reel weighs approximately 0.4kg and is designed for repetitive reinforcement tying in precast concrete, foundations, bridges, retaining walls and other reinforced-concrete construction.
The wire is manufactured from Q195 galvanized low-carbon steel with a listed tensile strength of 420MPa, yield strength of 330MPa and elongation of 17%. The combination of wire diameter, ductility and surface condition is intended to support consistent feeding, bending and twisting in compatible tying machines.
KYA lists this reel for legacy MAX RB392, RB395, RB397 and RB213-type applications. Automatic rebar tying tools use model-specific reels and spool geometry, so buyers should confirm the exact tool model and reel dimensions before replacing an original consumable.

The number of ties produced by one reel is not fixed. Wire consumption changes with tool model, number of wraps, rebar diameter and the size of the reinforcement intersection.
The wire has a nominal diameter of 0.80mm, corresponding to the 21 gauge wire class used by many conventional automatic rebar tying systems.
Wire diameter is only one compatibility parameter. Reel outside diameter, hub geometry, wire path, reel width and the tying tool's feed system must also match before a replacement reel is used.
Each KYA reel is listed at 100m of 0.80mm wire with an approximate net wire weight of 0.4kg. This format is intended for repetitive automatic tying applications where a pre-wound reel is loaded directly into a compatible rebar tying machine.
When replacing another manufacturer's reel, compare both wire length and spool dimensions. Different automatic tying systems may use similar wire diameters while requiring different reel structures.
KYA specifies Q195 low-carbon steel for this automatic tying wire. Low-carbon wire is used because the fastener must bend and twist repeatedly during the automatic tying cycle without excessive brittleness.
The galvanized surface adds corrosion protection to the underlying steel and provides a smooth finished surface for handling and feeding through compatible equipment.
Galvanized wire should not automatically be treated as suitable for every highly corrosive, marine or chemically exposed environment. Where long-term corrosion performance is critical, confirm the specified coating and project requirements before ordering.
| Mechanical Property | KYA Listed Value | Relevance |
|---|---|---|
| Tensile Strength | 420MPa | Reference wire strength before failure under tensile loading. |
| Yield Strength | 330MPa | Reference point at which permanent deformation begins. |
| Elongation | 17% | Indicates the listed ductility available for bending and twisting. |
Mechanical-property values should be considered together with wire diameter, surface condition and spool quality. For projects requiring certified mechanical properties, request the applicable production or test documentation with the order.
KYA lists approximately 120–190 ties per 100m reel. Actual wire consumption varies because different automatic rebar tiers use different numbers of wraps and different lengths of wire around each reinforcement intersection.
| Factor | Effect on Reel Yield |
|---|---|
| Tool Model | Different machines feed and twist different lengths of wire per tie. |
| Number of Wraps | More wraps consume more wire and reduce ties per reel. |
| Rebar Combination | Larger intersections require a longer wire loop. |
| Tool Adjustment | Tie settings can influence wire consumption and final tie geometry. |
KYA lists this 0.80mm reel for MAX RB392, RB395, RB397 and RB213-type applications. MAX documentation confirms that conventional Re-Bar-Tier models such as the RB397 use 21 gauge / 0.8mm tie wire.
MAX also specifies proprietary tie-wire reels for its rebar tying tools. Buyers replacing an original MAX reel should therefore verify reel geometry and tool compatibility before purchasing third-party replacement wire.
| Tool Reference | Procurement Check |
|---|---|
| MAX RB392 | Legacy model listed by KYA. Confirm reel dimensions and wire specification before substitution. |
| MAX RB395 | Legacy model listed by KYA. Confirm exact reel and feed-system compatibility. |
| MAX RB397 | Official MAX documentation specifies 21GA / 0.8mm wire; verify replacement spool geometry before use. |
| MAX RB213 | Listed by KYA; provide the exact tool identification or original reel specification when ordering. |
| Other 21GA Rebar Tiers | Do not assume compatibility from wire diameter alone. Confirm reel size, hub and feed path. |
Automatic tying wire is used to secure reinforcing steel and compatible reinforcement components during concrete construction before concrete placement.
Precast concrete beams, panels and components
Building foundations and footings
Rebar cages
Road and bridge reinforcement
Retaining walls
Concrete floor reinforcement
Wall reinforcement
Swimming pool reinforcement
Radiant heating tube fixing where permitted by the installation system
Electrical conduit fixing where permitted by the project specification
Automatic rebar tying tools are commonly used in precast plants where repeated reinforcement intersections must be secured before concrete casting.
For production purchasing, consistent reel dimensions, wire diameter, ductility and surface condition are important because frequent feed interruptions can affect the efficiency of repetitive tying operations.
The wire can be used with compatible automatic tying equipment during foundation, footing, column and reinforcement-cage preparation.
Tie wire holds reinforcement in position during handling and concrete placement. The structural performance of reinforced concrete is determined by the designed reinforcement system rather than the tie wire itself.
Automatic tying wire can support repetitive reinforcement work in bridge decks, pile caps, road structures and other reinforced-concrete projects where compatible tying machines are used.
For infrastructure projects with specified coating, material traceability or corrosion requirements, confirm the required wire documentation before ordering.

No. Wire diameter alone does not determine compatibility. The reel body, hub, width, winding and feeding geometry must match the tying machine.
Galvanizing provides additional corrosion protection compared with uncoated steel, but it should not be described as permanently rust-proof. Performance depends on coating specification and environmental exposure.
Yes. Foundation reinforcement is one of the typical automatic rebar tying applications when the wire and tool meet the project requirements.
Yes. Automatic rebar tying is widely used for repetitive reinforcement work in precast plants.
Road and bridge reinforcement are among the listed applications. Confirm any project-specific coating, material or traceability requirements before purchasing.
No. Tensile strength is only one factor. Feeding performance also depends on elongation, surface condition, wire straightness, spool winding, reel geometry, tool condition and machine adjustment.
OEM reel, wire length and packaging requirements can be discussed for bulk orders. Provide the tool model and required spool dimensions when requesting customization.
